GEORGE N. CLEMSON, OF MIDDLETOVN, NEW YORK.

SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 343,756, dated June 15,1886.

Application filed March 25, 1886.

To all whom it may concern.-

Be it known that I, GEORGE N. OLEMsoN, of Middletown, in the county ofOrange, in the State of New York, have invented a new and usefulImprovement in Sash Fasteners, of which the following is aspecification, reference being had to the annexed drawingsfiorming'apart thereof, in which Figure l is a plan View of my improvedsash-fastener. Fig. 2 is a vertical transverse section taken on line ata" in Fig. -1.

Similar letters of reference indicate corresponding parts in bothfigures of the drawings.

The object of my invention is to'provide a simple and efiicientsash-fastener which will secure the upper and lower sashes in a closedor approximately closed position; also, to provide means for preventingthe engagement of the fastener with the middle or top rail of the uppersash as one sash is moved past the other.

My invention consists in a spring-acted latch pivoted to a horizontalplate, with a nib projecting beyond the edge of the plate, and a rollercarried by the latch and projecting beyond the edge of the nib, to carrythe latch past the rails of the upper sash; also, in the combination,with the latch, of a catch provided with one or more notches forreceiving the nib of the latch when the sashes are closed.

To the base-plate A is pivoted a horizontal latch, B, upon the screw orrivet 0, passing th rough the latch and secured in the base-plate.

Upon the side of the latch B, near the free end thereof, is formed anib, D, which projects beyond the edge of the base-plate A, and at theend of the nib is formed a stud, E, for receiving the roller F, whoseperiphery projects beyond the edge of the nib D. The free end of thelatch 13 is provided with a lug, a, forming, together with the stud E, awide notch, b, for receiving the pin 0, projecting from the base-plateA; A ii at spring, G, secured to the base-plate A, near the pivot G,presses against the free end of the latch B and tends to keep the log aof the latch in contact with the pin 0, thus keeping the nib D and theroller F projected normally beyond the edge of the base-plate A.

To a base-plate, II, is secured astandard, I, in the edge of which areformed \l-shaped Serial No. 196,535. (No model.)

notches d d, for receiving the edge of the nib D. The base-plates A Hare provided with countersunk holes for receiving ordinary screws forsecuring them to the sash. The base-plate A is secured to themeeting-rail of the lower sash with the nib D projecting over the outeredge of the rail, and the base H of the catch is secured to themeeting-rail of the upper sash, with the notched standard I in the pathof the nib D. so that when the upper sash is raised or the lower sash isshut down the nib D will engage one or the other of the notches (Z d inthe standard I. If the windows are prevented from going to their placesin the window-frame by ice or some other ob struction, the nib D will bereceived in the notch d,and the window will still be securely locked.WVhen the sashes are slid past each other in opening the window, the nibD is prevented from striking the rails of the sash by the engagement ofthe roller F with the rails, which pushes back the latch B and carriesthe nib D past the rails without touching them.

The roller F is preferably made of elastic material or provided with acovering of elastic material, which prevents injury to the sashrails byengagement with the roller.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination, in a sash-fastener, ofa base-plate, A, aspring-acted latch, 3, pivotedthereto and provided with a nib, l), andstud E, the rollcrlfijournaled on the stud, and the catch consisting ofthe standard I, provided with notches d 11, substantially as hereinshown and described.

2. The combination, in a sash-fastener, of the base-plate A, providedwith the pin 0, the latch B, pivoted to the base'plate and provided withthe nib D, the stud E,and lug a, the roller F, received on the stud E,the spring G, se cured to the base-plate A and pressing the latch B, andthe catch formed of the base-plate H and standard I, provided withnotchesd d,

substantially as shown and described.
